Description

RFID data acquisition and use
Technical field
The present invention relates to use the collection and the use of the data of RFID tag.
Background technology
REID (RFID) has been suggested and has been used for many application, and wherein, a RFID label is over an item attached, thereafter, inquires or reads to obtain the information of relevant this project.For example, PCT publication Nos.WO00/10144 and WO 00/10122 describe the various function and applications of rfid system, and exemplify the application of RFID label in the library.U.S. Patent No. 5,963,134 also describe rfid system some use in library and other application.The present invention relates to use RFID label and system that data are gathered and managed.
Summary of the invention
The collection of the data that the present invention relates to use RFID reader interrogating rfid label and obtain and all many-sides of use, wherein, each label is relevant with an interested project.In certain embodiments, preferably adopt portable reader, be preferably hand-held RFID reader and inquire project through the RFID-label.In general, the present invention relates to the collection and the classification of data, the bulletin in the inquiry process, catalogue, the background catalogue, catalogue is coordinated in real time, changes error margin allowable, and the conversion of the project of the project of non-RFID-label and RFID-label.For example, various projects can be assets, evidence, articles from the storeroom, distribution or facility, tray or storage container, official document, file (file and the record that comprise patient or client) commercial, retail or that store, and mail (comprising envelope and parcel).
Embodiment
1. universal RFID information
The RFID label is well-known with the reader that is used for this label in the present technique field.For example, the RFID label can be buied with " Tag-It " trade name by the Texas Instruments Company company of the Dallas of Texas, and reader also can be buied with trade name " Commander " especially from Texas Instruments company.U.S. Patent No. 6,232,870 (people such as Garber) introduce the embodiment of a useful especially RFID reader, wherein, one portable integrated RFID reader comprises an antenna, a computing machine, a display, and a RFID reader that is used to interrogate the RFID label.The content that this paper quotes following patent is for your guidance: United States Patent (USP) 6,232,870, PCT publication No.WO 00/10122 and PCT publication No.WO 00/10144.The present invention relates to use the method for RFID reader, and use this method once the information that obtains from RFID label acquired information.These aspects of the present invention and other aspect will be explained in detail below.
The useful function of one RFID reader is to collect data.That is, when the RFID reader was interrogated a RFID label, the information that relates to the project relevant with label was collected and is stored in the database.This database can be placed in the storer of RFID reader, (for example be placed on the movable data memory that links to each other with the RFID reader, the volatile storage card), is placed in the storer such as another equipment of computing machine, perhaps is placed on more than one these position.The RFID reader can be the above-mentioned type or as patent ' the portable reader described in 870, perhaps, it can be the parts such as another equipment of the checking item turnover catalogue, perhaps, it can be by obtaining the information of relevant this project, the RFID label relevant with this project is provided then, the project of bar code or other identification converted to the project of RFID label.
Some aspect of the present invention can the library environment as an example, wherein, rfid system can seem useful especially.Yet, scope of the present invention is not limited to the library, and can be used for other suitable environment, comprising tracking (but being not limited to): assets, evidence, articles from the storeroom, distribution, commercial, retail or the facility, the tray that store or store container, official document, file (file and the record that comprise patient or client), and mail (comprising envelope and parcel) to following items.According to disclosed content provided by the invention, in the present technique field technician obviously will understand the present invention above-mentioned with other purposes.
2. data acquisition and classification
In one aspect of the invention, data can gather and be categorized into each classification and be stored in the database.The classification that certain project is used is meant the cohort of all projects with particular characteristics, and only represents the part (though may be a main portions) of the whole cohorts of RFID tag entry purpose.The RFID reader can be provided with interested some the default classification of user, or the user can define the attribute that falls into all projects in the class scope.For example, if the user uses the reader in the library, then default classification can be some position (bibliography, non-novel or novel) in the library, or the type of project (book, periodical, sound/video display reading matter etc.).Define or customized classification can comprise and (for example be used to be considered in a certain way, be used in the library and not for circulation, or be used for the purpose of classroom or program, or link mutually with the audio or video player) classification of used project, or by be used for special-purpose by the user and other classification of design.These classifications can be defined or offer the RFID reader by the user interface such as the display with data input capability, or by uploading from the removable data storage medium, or pass through from (for example connecting, by line, docking station, or wireless mode) in the Computer Database of RFID reader, upload.
In case certain classification is chosen or definition, the RFID reader can be used to inquire the RFID label that is connected with relevant item.Classification can be got well several modes and be carried out.First kind of mode of the project of classification RFID label is (for example to select, from the classification inventory that shows for the user) or define a classification, the RFID label that inquiry and relevant item are got in touch, then, the information storage that will obtain from the RFID label is classification selected or definition in database.This project and classification with the RFID label connects.Then, the user can continue to inquire with this classification in the project RFID label of getting in touch, or switch in another classification and go.For example, one user in the library can select or define one " only using not for circulation " classification in the library, then, and the relevant RFID label of project that inquiry and user in the library stay, and then, store this information in the classification of " the indoor use " in database.If the user wishes to change classification then, then the user can select or define another classification (for example, " being used for reading room for children "), then, and inquiry project and they are stored in the classification in the database.Database can be the interior database of storer that is stored in the RFID reader, (for example be stored in the interior movably data storage device that is connected with the RFID reader of the storer that is connected with separately computing machine or miscellaneous equipment, flash memory cards), or in the suchlike equipment.
The second way of the project of classification RFID label is to select or at least two classifications of definition, uses a RFID reader to inquire at least one RFID label project, then, and with this project and one or more classification associated.That is, can be to dissimilar projects, or, create classification to project with to inquiring (the therefore project that can often use) recently or not having the project of inquiry with different inventory status (for example, exist and do not exist).Whether have the feature of the project of classifying according to projects in classification separately, the project of RFID label can be categorized into zero, one, or more than one classification.Classification can be mutually exclusive (meaning that each RFID label project only can be sorted in the classification) or do not repel.
The third mode of the project of classification RFID label is to select the project of at least one classification; The inquiry relevant item the RFID label wherein at least one in project category; The project of RFID label and suitable classification are connected.That is, project and classification that the RFID reader will have certain characteristic connect, and omit any project with these characteristics.Therefore, if a user interest only has on the project of certain feature, then the RFID reader can be created the only inventory of these projects, and does not list or sort out any other the project with particular characteristics.For example, if a user in the library, its interest is only at acquired information from the project of certain type, and for example, bibliography then can be set up the classification of bibliography, the project of interrogating rfid label, and only be sorted in bibliography in the classification.The classify needed information of label project (at the embodiment of this embodiment and other) of each RFID, can obtain from RFID label itself, or from the database that comprises the record that relates to RFID label and/or project, obtain, for example, be stored in database in the storer relevant with the RFID reader.This storer can be integrated, maybe can be the movably data storage device such as flash memory cards.
3. informing in the inquiry process
In data acquisition, the RFID reader can provide feedback sound and/or image to indicate (a), and when the RFID reader is in reading tag, (b) when the RFID reader detects project on the predetermined item inventory, and/or (c) when detects not the RFID label with entries match in existing data base.For example, one light indicator can indicate when the RFID reader is successfully inquired, the signal of one sound can indicate a project on the predetermined item inventory and be detected, or one also can indicate the RFID label of the entries match in the existing data base of having inquired not with project such as the signal of light or sound.Signal also can be arranged on the user interface such as display, and this user interface can to make the user be establishment of item one data-base recording, and/or the input information relevant with project.For example, user interface can comprise a keyboard touch-screen display and/or a reality or simulation, the user can be this establishment of item data-base recording by them, and/or by the user interface input information, the identifier of the project of the type of this user interface description project, its name or title, certain type, or other information.
4. make a catalogue
The purposes that also has is to use the RFID reader to make a catalogue with the RFID label that links to each other with related item.The information that the RFID reader is gathered related item by the inquiry RFID label relevant with project.Yet, if this information only is listed in the database, so that project is inquired, so, if single project is not in position, for example in 1000 projects, then when should " inquiry inventory " comparing with predetermined order, the result shows that 1000 projects of insertion have at least a position in position not go up.For example, if in the library, a book is not in position gone up, because 1000 books are on the left side of its correct position, then, the inventory of inquiry can indicate the book of 1000 insertions and not go up in place.This can cause extremely inconvenient huge, therefore utterly useless to the user of paper of printing or the data of listing.Moreover it only is not in position project of several position that the certain user is indifferent to.This situation can be quite general, and for some people who seeks project, do not have problems usually, because the position of its hope of project close enough.Yet the report of the catalogue of a standard can be listed nearly all project that does not in position go up, even also lists those only orderliness projects of difference slightly.
Also has other equipment, the mistake of their report items storing positions such as hand-held RFID reader.For the user who uses such equipment, one describes the catalogue that the has or not report of positional fault and project, and it is useless to become.These users may bias toward the information of other classification in the report such as leaking.
In order to overcome these possible difficulties, when a catalogue report comprises the information that is not in the right order mistake or undesirable, one method is provided, wherein, the RFID label that inquiry and related item are got in touch, then, place data in an orderly manner according to the order (it can be referred to as the algorithm order) of its hope, orderly with project again inventory (or project list of algorithm order) relatively.This comparison can make processor determine which RFID reader wishes that the project of inquiring loses, and which RFID reader does not wish that the project of inquiry (because database indicates them and do not exist) exists.For example, the synthetic normally useful length of inventory of the project that (undesirably) loses and (undesirably) exists thus, overcomes above-mentioned many difficulties.
This use and other application in, order can be traditional with respect to the relation of the project of seeking information (for example, Du Wei (Dewey) decimal system or be used for the system of Library of Congress of library materials), maybe can be to be specified by the user.The inventory of any or all descriptions can be stored in the database, database can be placed in the storer of a computing machine that links to each other with the RFID reader, or be placed on movably data storage media that the RFID reader links to each other in, or be placed in the storer that links to each other with independent computing machine or equipment.Perhaps, can be collected simply, and can place the time afterwards, or collect, or both have both at the same time, all before or after information has been stored in the database by different computing machines with the order that requires from the information of RFID label.
5. background is made a catalogue
In another embodiment of the present invention, catalogue can side by side carry out with other operation of rfid system.That is, be known as by the inquiry project and carry out RFID tag entry purpose catalogue for this purpose.In this embodiment of the present invention, use the data that obtain as various objectives, carry out the background operation that is categorized as rfid system.For example, a portable RFID reader can be used to inquire the project in the storage area, whether is positioned at suitable order, position to determine them, or both have both at the same time, and perhaps whether they are present on the inventory of user's interest project.This is the fundamental purpose of RFID inquiry, also can be used for carrying out catalogue but relate to the information that these projects obtain.That is, whether be in each RFID label project that suitable order is inquired for determining it with respect to contiguous project, also necessity is present in the storage area, therefore, as required, can seek advice from the database with updating inventory, the fact that exists with the reflection project.The operation of this background catalogue also can be used for the hardware of other RFID, for example, and the equipment that registration is advanced/gone out, switching station (be used for the project of no RFID label is converted to the project with RFID label, all labels link to each other with project), or other this type of equipment.In these examples, main operation can be a project of verifying the turnover storage area, or a project is converted to the project of RFID label, but catalogue (operation for the second time) also can be carried out in background, perhaps notifies a user whether not to be rendered as the order of hope according to an order inventory of project for the project of conversion usefulness.
Although above-mentioned catalogue has been described as operation for the second time, same principle is applicable to the combination of other first and second operations.For example, when whether being in suitable order (first operation) when identifying project, a RFID reader also can be sought the project on the predetermined inventory of project (second operation), for example, be considered to lose, damage the project of the grade that keeps for client.Perhaps, when a RFID reader is used for inquiring the RFID label relevant with project, and help the user to identify project to belong in the storage location (first operation) where the time, as mentioned above, the RFID reader also can be sought all projects on the predetermined inventory of project.The various functions that are described as first operation or second operation can be exchanged or with being connected with suitable manner of any requirement, like this, being that the information that a purpose is collected is used as another purpose, and not needing interrogating rfid label again.Also can in first and second operations, as requested, carry out that other describes the extra operation of type Anywhere herein.
6. catalogue is coordinated in real time
In the relevant embodiment of the present invention, a portable RF ID reader can be carried out real-time catalogue and coordinate.That is, portable RF ID reader reads the RFID label that is positioned at such as the project of the storage area on frame, then, and the inventory of the project that comparison detection arrives and based on the content of the expectation of the storage area in the inventory data base.One inventory data base can be stored on the movably Data Holding Equipment such as a flash memory cards, maybe can be stored in the storer of a part of portable RF ID reader, or be stored in by the real-time connection of wireless connections or alternate manner in the accessible database.These inventory data bases can be stored in chief editor's order data of a central computer, network etc. from one and separate, and chief editor's order data can be upgraded continuously or off and on by real-time data base.What in real time inventory information can offer a user is, relates to the former project that should find but not find, should not find originally but the project that found, or at the catalogue of reality be reflected in other deviation between the catalogue on the database.The state of project can upgrade according to the information that obtains from inquiry, and new state can be stored in the inventory data base.One useful especially being characterised in that of real-time catalogue, RFID reader can make the user determine that in the inquiry process particular items of not found (but wishing found) loses from the storage area.If the user confirms project and lose that then the RFID reader can be corrected inventory data base, lose (that is, not existing) with the project of indicating.Conversely also can be useful-make the user confirm found but think that in fact the particular items that is losing exists, therefore, correct inventory data base.No matter original inventory data base stores under which kind of situation, always can store the inventory data base of correcting.This real time coordination of catalogue is saved time, and therefore, is a useful feature in catalogue work.By any requirement in prompting user input and the database or the relevant data in option territory, can make the user to being inquired but any project that in database, does not find such as the user interface that is connected with a display, foundation or editing data storehouse record.This feature can make a user be corrected in incomplete record in the database with real-time mode.
7. the random groups of classifying
In library and other storage area, after using, project is turned back to a storage area, the energy that regular meeting's cost is suitable.These projects generally must be put back into suitable position and get on.This usually by after all projects of manual sorting, is put on the dolly, then, shuttles in the storage area, takes out the project of appointment from dolly, and they are replaced, for example, and on the frame of storage area.The purpose of embodiment is below the present invention, is used for the utility appliance of the robotization of this task.In this embodiment, can use a portable RFID reader to read and one group of RFID label that the projects of placing at random are relevant, and demonstrate the inventory of these projects of arranging according to predesigned order.This order can be the standard order that is used to organize the type (for example, being used for organizing the Dewey decimal system or the system of Library of Congress of library's material) project, or the order of customization.When the project team of RFID reader inquiry RFID label at random, reader can be organized the information of relevant these projects in an orderly manner, then, shows the inventory of project of the orderly arrangement of part or all.The information that is presented on the inventory can be the information that obtains from the RFID label of inquiring, the information that obtains from database, or both combinations.This inventory can be used to suitable order project is placed in the storage area, is placed on the dolly so that be transported to the storage area just as on their suitable positions that set of diagrams book shop material is put on the shelf again, or with project.The order that the present invention is convenient on request is placed on project on the dolly, and it is more effective to make project be put back on the frame original place, storage area.
8. change the allowance error tolerance limit
Some RFID reader can side by side be inquired several RFID labels in " read range " of reader.When these labels during basically simultaneously in response to the RFID reader, especially when RFID reader promptly during all projects of bypass, relative position accurately definite or that differentiate a plurality of RFID labels can become very difficult.Yet a portable RF ID reader can be determined the approximate order of the project that the RFID label is inquired.When using such RFID reader to come to a position, user report storage area or error (" order on the frame " error), the order of this approximate order and expectation compares.Because be included in the error of order on the approximate frame of project, so the error of order can be detected on the wrong frame, it can provide a Discrepancy Report, and it is annoying rather than useful report to the user.If error margin allowable increases, with the error that farthest reduces to report, then some detectable and significant error can be reported.The error specification that allows can be described as the order tolerance limit, or order tolerance limit on the frame.Of the present invention this specially refers to this possible problem on the one hand.
RFID reader of the present invention and method can be suitable for variation error report algorithm, especially change error margin allowable.Error margin allowable is the scope of position, and it is the scope of position of leaving the project expectation of the project that is allowed by algorithm.That is, the allowance error tolerance limit can be 1 position, and such one what move apart its desired locations is that the project of 1 position will be thought of as and be located in place by Discrepancy Report algorithm (so RFID reader).Moving apart its desired locations can be thought of as by algorithm greater than any project of 1 position and not go up in place or misplace.Therefore changing error margin allowable can make a user increase or reduce the scope of " acceptable " position of project.Whether this variation can according to being that approach, medium by the project that be inquired, or thick and decide.That is, the resolution of RFID reader enough accurately makes reader can survey the relative position of thick project (for example, encyclopedia, reference book etc.) reliably usually.In these cases, the user stipulates that this thick project inquires, be littler deviation between the position of the position of detection and expectation and revise error detecting algorithm with error classification.For the thin project such as children's book or periodical, the resolution of RFID reader may accurately detect the relative position of the project of tight spacing inadequately.In these cases, the user stipulates that this thin project inquires, be those errors owing to enough dislocation placements reliably significantly rather than bad resolution and revise error detecting algorithm with error classification.Although can use regulation " thin ", " medium " and " thick ", and be effectively,, also can use digital expression (for example, from 1 to 30) or other representation certainly because the user can easily understand these terms.If use the tolerance limit of a numeral, then numeral can be similar to the number of per unit metric terms, for example, per inch, centimetre, or the numeral of foot project.Therefore, algorithm can according to make amendment near near the feature of project relevant the RFID label of project; Usually make amendment according to the width of project.The change of allowance error tolerance limit can be undertaken by the user interface that comprises display (for example, touch-screen display), button etc.
The feature of above-mentioned transformable resolution also can automatically be carried out, rather than is operated by the user.That is, the RFID reader moves through project with certain " normally " speed usually in the process of inquiry, and it can approximately be 2 projects of per second in the situation of library materials.The RFID reader can be programmed, to infer when project is to be inquired greater than normal speed, reader moves through the thin project (that is, the user moves reader by project with approximately uniform speed, but the per unit length of storage area is by more project) of greater number.Then, reader can dynamically be adjusted error margin to the project that dislocation is placed.For example, if the normal speed of RFID reader inquiry project is 2 projects of per second, and the RFID reader begins to inquire 5 projects of per second, and then the RFID reader can change error margin, like this, the project in 2 positions is positioned at the both sides of desired position+/-2 positions to+/-5 positions.Vice versa, like this, if inquiry speed is per second 1 project, then error margin can be automatically from+/-2 change in location to+/-1 position.The variation of error margin can be proportional to the rate variations of inquiry, or becomes direct direct ratio, or becomes geometric proportion, or according to other variation of inquiry speed.
If the RFID reader can not as propose in the example inquiring speed interrogating rfid label reliably faster, the above embodiments then of the present invention are difficult to implement.That is, some RFID reader can not be inquired with per second 5 projects, on the contrary, can continue to read per second 2 projects, and can not successfully inquire other 3 projects.In above-mentioned example with other, resolution still can be changed or automatically be changed by the user.This can implement by the RFID number of tags of measuring " reading range " that be positioned at the RFID reader simultaneously.For example, if the reading range of RFID reader can enough detect the label in around the shelf at reader center six inches, then in the part of " common " books, the RFID reader can side by side detect six RFID labels.In the zone of one " approaching " project, the ##RFID reader can side by side only detect 3 labels.Measure according to this, the RFID reader can automatically be adjusted order tolerance limit on it to each shelf dividually by an algorithm.As above-mentioned embodiment, even can dynamically adjust, like this, comprise thin project on the end and the other end comprises the shelf of thick project, can handle with different tolerance limits the different piece of shelf along with scanning to shelf.In a word, the variation of error margin can be proportional to simultaneously the number of tags that detects, or be directly proportional in, or become geometric proportion, or according to other variation of the measurement number of label.
9. non-RFID label project is transformed into RFID label project
The convenience of seeking exception in the transfer process that relates in one aspect in addition of the present invention.The term that has used herein " conversion " generally is meant non-RFID label project is transformed into RFID tag entry purpose process.In the useful embodiment of a switching station, but scanning bar code or be used in other project-ID on the project or be input in the processor, this processor can utilize this information to set up the RFID label that will get in touch with this project in the database.Out of Memory the information in the existing data base that relates to this project also can be used for the RFID label of setting up for this project.This information can comprise the type (no matter whether this project is capable of circulation) of project, the file of this project or the data of breaking-up, or other such information.Then, the RFID label can be placed in the project, and on request project is handled.According to necessary inverted term purpose number, transfer process can be expensive, but the general sufficient value to some extent of the benefit that accompanies.
Being transformed in the process of RFID label in the project that will collect, is that the present invention is at the theme aspect this in order farthest to reduce the unnecessary a kind of method that expends.In this embodiment, switching station is implemented an additional step,, determines that non-RFID label project is whether on the inventory of project that is, or in the classification of the project that should not change (or determine convertible project whether on the inventory of project, or in answering the classification of inverted term purpose).That is, control personnel and the entity that non-RFID label project collects and to determine some project not need conversion, perhaps because the benefit of conversion expending of can not confirming to change.Below all kinds of project promptly be this situation, for example, project early, the project that often occurs or not from obsolete project, the project of damage, the multiple of same project duplicated, and has the short shelf life-span (for example, periodical) project, or suchlike project.The project of these types can individually be enumerated according to the information in the existing data base, or can enumerate (for example, " surpassing the project in 5 years ", or " project of damage ") according to rank.When switching station accept sign presented to switching station with the data of the project of doing conversion (by scanning a bar code, optically read characteristic, acceptance is by the data of operator's input, or the data of alternate manner acquisition) time, it determines whether the project that has identified is not suitable for conversion (whether the project that perhaps, has identified is suitable for conversion).If then switching station sends the signal of this state of expression.If not, then can change.Like this, only have the project of minimum number need be converted to the project of RFID label, it causes the saving of time and money, particularly to otherwise can become the project of RFID label and the project that in the near future from collect, abandons then.
In a certain embodiments of the invention described above, can set up a user and not wish to be transformed into RFID tag entry purpose project database (or particular items, or can by the feature of the project of determining in the information of known these projects).Perhaps, can set up the database that a user do not wish to be transformed into the exclusive project of RFID tag entry purpose (or particular items, or can by the feature of the project of determining in the information of known these projects).In any situation, this database can be transferred to (by downloading, or upload) from the removable data storage facilities, or otherwise can be to the switching station access, then, the information that obtains from the non-RFID recognition system relevant with projects can compare with database, whether should be transformed into the project of RFID label to determine this project.
In the process of RFID label, also can carry out other operation in the non-RFID label project of conversion.For example, when project was changed, the inventory of inventory by relatively presenting the project that is used for changing and the current project that indicates at database can carry out the catalogue of project.Can produce the inventory of supposing the project that loses to a user from this information.Enforceable other operation is in transfer process, and it is suitable, expectation whether the project of determining to present conversion is in, or the order of algorithm.Why this may its reason be, in the process of conversion, a user from select one first project such as the storage area on the shelf in library, presents to switching station with this project usually, then, the acceptance RFID label relevant with project with application is on project.Then, the user replaces the project on correct position in the storage area, and selects next project.If the user changes project in order, the order of the project that then presents exactly (projects are positioned at position accurately) or approx (projects are positioned at the position of specified quantity with respect to the position of expectation) compare with inventory expectation, project suitable or algorithm.Switching station can inform that then project that when user change is not accurately or approximate order.
10. mate and the storage inventory
Patent ' 870 discloses a RFID reader, if the information of related item does not offer the RFID reader, then this reader can be used to seek RFID label project in a storage area.If the information of relevant one group of such project offers the RFID reader incipiently, for example, one group or list or other identifier, then, but RFID reader interrogating rfid label project, whether the project of determining inquiry mates with any project on inventory, if then storage relates to occurrence purpose information.For example, the inventory of a related item can offer the RFID reader, and given one identifier such as " losing project ", to identify the former project that should be present in the storage area but not find as yet at present.In this example, if the RFID reader runs into the RFID label relevant with the project in the storage area with inquiry, and this label comprise with " losing project " inventory in the information that is complementary of clauses and subclauses, then the RFID reader can be referred to as the information that is checked through or the information stores relevant with the RFID label of inquiry in the database data aggregation classification of " losing project " from the RFID label of inquiry.This data storing operation can automatically be carried out, or after the user of prompting RFID reader, and the database of catalogue can carry out continuous or regular renewal with acquired information.The project list that can be referred to as " searching inventory " can be such project, and user or client wish its location and lend, or use, or destroy, or file, or shift.Owing in the storage area, seek such project, user to this type system is useful, so, if this automatic data acquisition ability can not reach, then the user can need to keep this project in order to later processing, maybe can make special effort and come the information (as previously described) of " manually " storage about this project of the data acquisition ability of certain type of use.Therefore, the energy that embodiments of the invention can save time and RFID reader user need spend.
